hi this line giving error:

`
  fileprivate var width : Int {
    return ((buttonHeight + spacing) * maxRating) - spacing
  }
`
tells that:
Property 'width' with type 'Int' cannot override a property with type 'CGFloat'

i tried to change return type. this time it compelling about 'we cant override a read only property named width.' you may need to change the name of this property.
